Ukraine signs buffer zone deal with rebels

 Ukrainian forces and pro-Russian militias were due Saturday to pull back their troops from a demilitarised zone created under a new peace plan agreed in marathon overnight talks, AFP reports.

A nine-point agreement thrashed out in the early hours of Saturday in the Belarussian capital Minsk also requires the withdrawal of all "mercenaries" from the conflict zone and an immediate end to hostilities.

But Russia appeared ready to keep up the pressure on its westward-leaning neighbour by sending in a new 30-truck convoy it said was carrying aid for the rebel-held city of Donetsk, but that Ukraine never approved.

Former Ukrainian president Leonid Kuchma -- who is representing Kiev in the stuttering efforts to resolve the five-month conflict -- said the agreement rested on the creation of a 30-kilometre (19-mile) buffer zone.

Forces from both sides are required to retreat 15 kilometres from current frontlines within 24 hours of the signing of the accord and allow monitors from the OSCE pan-European security organisation into the area to make sure the truce holds.

The areas under rebel control would be left open to their administration under a temporary self-rule plan adopted by lawmakers in Kiev on Tuesday.

The Minsk pact -- also signed by Moscow's ambassador to Kiev and the self-proclaimed "prime ministers" of the rebel-run regions of Donetsk and Lugansk -- aims to shore up a ceasefire deal agreed two weeks ago.

The agreement crucially requires both sides to immediately withdraw "foreign mercenaries" from the conflict zone in industrial eastern Ukraine.

Kiev and Western allies accuse Russia of clandestinely slipping at least 1,000 paratroopers into east Ukraine to help the guerrillas mount a surprise counter-offensive late last month.

The Kremlin denies ordering soldiers into Ukraine. But Moscow's Kiev envoy Mikhail Zurabov told Russian media after the signing of the Minsk deal that both sides appeared to have hired foreign mercenaries.

The sides agreed to leave the most divisive political issues for future negotiation in order to get the terms of the truce worked out first.

Donetsk separatist leader Alexander Zakharchenko stressed that the explosive question of the status of rebel-held Donetsk and Lugansk was not discussed in Minsk by mutual consent.

"We each have our own understanding of (Kiev's) law on special status," Russian media quoted Zakharchenko as saying.

"These are issues for future negotiations that will last another year."

  New Russian convoy 

The elusive ultimate goal is to find a lasting solution to a conflict that has claimed nearly 3,000 lives and stoked Western alarm about Russia's territorial ambitions.

The talks came in the wake of a peace overture by Ukrainian President Petro Poroshenko that included a limited self-rule offer for separatist-controlled areas in the east and an amnesty for all fighters.

The offer was welcomed in Moscow but treated with caution by rebel commanders who had been seizing back large swathes of territory from Ukrainian forces in the days preceding the September 5 truce.

The ceasefire has helped calm the worst fighting but continues to be regularly broken around Donetsk -- the scene of almost daily shelling on the city's outskirts -- and other disputed parts of the Russian-speaking industrial heartland.

Rebel representatives in the city of nearly one million -- now with neighbourhoods abandoned by families devastated by constant shelling and food shortages -- said they had received a Russian humanitarian convoy overnight.

The press service of the self-proclaimed Donetsk People's Republic said the volume of aid "was very large" but provided few other details

Moscow had twice before overlooked concerns in Kiev that the shipments may be hiding weapons or other supplies for militias and ordered the trucks across the border without its neighbour's permission.

  NATO readies response 

The Minsk meeting came at the end of a dizzying week for Poroshenko that included Ukraine's ratification of a landmark EU association agreement for which he personally lobbied and a visit to Washington for talks with US President Barack Obama.

But the 48-year-old chocolate baron failed to convince Obama to become more directly involved in resisting Russia's "aggression" by providing Kiev with offensive arms.

The United States instead approved an additional $46-million non-lethal aid shipment that will provide Ukraine with equipment such as night vision goggles and bullet-proof vests.

Poroshenko had told a joint session of Congress that aid such as "blankets" could not help his army with the war.

Ukraine was still set to receive an important boost from the 28-member NATO military alliance when its defence chiefs gather Saturday in the Lithuanian capital Vilnius for a three-day meeting focused on ways to counter Kremlin's expansionist threat.

The Western military alliance is due to set up regional command centres in eastern Europe that would help coordinate the actions of a rapid-response "spearhead" force approved by NATO earlier this mont.
